Definition of given that

The term "given that" is a logico-mathematical phrase used to introduce a condition or assumption that is considered to be true or established in the context of a mathematical statement or argument. The etymological origin of the phrase can be traced back to the Middle English period, around the 14th century. The phrase "gon" was used at that time to indicate the past participle form of the verb "gan," which meant "to begin" or "to start." This usage evolved into the contemporary verb form "gone" and was commonly employed in various grammatical constructions, including conditional clauses. In the case of "given that," it appears to have originated as a syntactically appropriate substitute for "supposing that" or "provided that," given its grammatical properties and mathematical context. Over time, "given that" became increasingly popular due to its concise and unequivocal meaning, making it a widely adopted phrase utilized in mathematics, logic, and other related fields.
